Number Please?

A cross-number puzzle on a 3 x 3 board. Nine digit keys wait in the tray. Put each one in a square so that every row and every column, worked left to right and top to bottom with no precedence, reaches the total shown at its end. The signs between squares are chosen at random from plus, minus, times and divide. HINTS, from 0 to 3, sets how many squares are already given and locked. Any arrangement that makes all six lines right is accepted. A game is five calls. Each call allows three checks, and a right board scores more the fewer hints and checks you used. After a wrong check each line shows a tick or a cross. A third wrong check shows the answer and moves on.

Controls: Use either controller. Move the cursor with the stick; a button picks up or puts down a key, and the CHECK plate checks the board. On the title, up and down choose a line, left and right change the hints, and a button starts.
